Live aurora visibility, KP index and best viewing time for Reykjavik and all of Iceland — updated every 2 minutes from NOAA.

Iceland sits directly under the auroral oval, making it one of the best places on Earth to see the northern lights. But seeing the aurora is never guaranteed — it depends on three key factors: solar activity (KP index), clear skies, and darkness.
AuroraVision combines live NOAA satellite data with local weather forecasts to give you an accurate visibility score for your location in Iceland — updated every 2 minutes.
The KP index measures global geomagnetic activity on a scale of 0–9. Here's what each level means for Iceland:
The further you get from city lights, the better your chances. Top spots near Reykjavik include Þingvellir National Park (45 min), Grotta Lighthouse (10 min), and Kleifarvatn lake (30 min). Further afield, Snæfellsnes Peninsula and North Iceland offer exceptional dark skies.
The aurora season in Iceland runs from September to March when nights are properly dark. The peak months are October, November, February and March — longer darkness, higher solar activity, and calmer weather windows. The summer months (May–July) have no aurora visibility due to the midnight sun.
1. Check the forecast — Use AuroraVision's live visibility score before going out.
2. Get away from city lights — Drive 30–45 minutes from Reykjavik.
3. Wait for clear skies — Cloud cover is the biggest enemy of aurora viewing.
4. Go late — Peak aurora activity is between 10pm and 2am.
5. Book a guided tour — Guides track conditions in real-time and know the best spots.

AuroraVision is the most accurate aurora forecast app for Iceland. It uses live NOAA data and local weather to calculate a real-time visibility score. Available on App Store and Google Play.
During strong aurora events (KP 4+), you can sometimes see northern lights from Reykjavik itself. But for the best experience, drive 20–45 minutes outside the city to reduce light pollution. Grotta, Þingvellir and Kleifarvatn are popular spots.
Guided tours add significant value — guides track multiple forecast sources, drive to optimal dark-sky locations, and know where conditions are best. They also provide hot drinks and photography tips. If you only have a few nights in Iceland, a tour increases your chances considerably.
